Taking a belly split from a stave with that much crown will cost you two rings, at least. It will yield a useless, other than as a bbo core upper split. If you have enough depth, unlikely with that much crown, you could do it but it only serves to reduce the time getting to the one good stave. And it risks that one good stave. I've got osage running outa my ears, and I'm tight as they come, and I would not take a belly split off that stave. I might take a core off the top with a bandsaw, but only if the stave was real nice and I had the chops on the saw to not cut into the good stave. JMHO.
